I'm using the below javascript to display a popup message on page load for a clients website. I am a real novice at js and can only really copy/paste examples I find on the net. Need to know how I can set the width of the popup box. I would like the text to run over two lines, not just span the width of the page. Here is an example of how it appears www.manageourwebsite.com.au
<body onload="WelcomeMSG()">
<script language="JavaScript">
<!--
function WelcomeMSG ()
{
alert("Our Retail shop front will be closed from Friday 21st December 2012 thru to Monday 21st January 2013. The Online store will be open 24/7 as usual with all online orders being processed as normal.")
}
-->
</script>
推荐答案
如果您希望将文本包装在两行上，我建议在文本中的所需位置添加\ n换行符:
If you wish to wrap the text onto two lines I recommend adding the \n newline character in the desired location in your text:
alert("Hello\nWorld")
